Drawbridge and Network Monitoring Info?

[Dave Conroy <dcon () iss ca>]

Hi all;

I have Drawbridge 3.02 running on a FreeBSD 2.2.8 machine providing Firewall
services for my network. I was wondering if there were anybody who had any
suggestions to provide some sort of 'Monitoring' application that can be run
on the same machine to see where traffic is going, if DoS attacks are sent
to a specific host; etc.

Any comments would be appreciated;

Thanks
